HIV drug resistance
The ability of HIV to mutate and reproduce itself in the presence of antiretroviral drugs is called HIV drug resistance. The consequences of HIV drug resistance include treatment failure, need to start more costly second- and third- line treatments, increased health costs associated with these, spread of drug resistant HIV, and need to develop new anti-HIV drugs.
WHO, and its partner organizations and experts of HIVResNet group have developed a Global strategy for prevention and assessment of HIV drug resistance. The strategy enables generating data on the emergence and transmission of HIV drug resistance and equipping countries with guidance on how to limit and monitor the emergence of HIV drug resistance.
